AIM :To write a python program for creating File Transfer using TCP Sockets Links.
ALGORITHM :
- Start the program.
- Get the frame size from the user.
- To create the frame based on the user request.
- To send frames to server from the client side.
- If your frames reach the server, it will send ACK signal to client otherwise it will sendNACK signal to client.
- Stop the program
PROGRAM :
CLIENT:
import socket
s = socket.socket()
host = socket.gethostname()
port = 60000
s.connect((host, port))
s.send("Hello server!".encode())
with open('received_file', 'wb') as f:
while True:
print('receiving data...')
data = s.recv(1024)
print('data=%s', (data))
if not data:
break
f.write(data)
f.close()
print('Successfully get the file')
s.close()
print('connection closed')
SERVER:
import socket
port = 60000
s = socket.socket()
host = socket.gethostname()
s.bind((host, port))
s.listen(5)
while True:
conn, addr = s.accept()
data = conn.recv(1024)
print('Server received', repr(data))
filename='mytext.txt'
f = open(filename,'rb')
l = f.read(1024)
while (l):
conn.send(l)
print('Sent ',repr(l))
l = f.read(1024)
f.close()
print('Done sending')
conn.send('Thank you for connecting'.encode())
conn.close()
OUTPUT :
CLIENT:
SERVER:
RESULT : Thus, the python program for creating File Transfer using TCP Sockets Links was successfully created and executed.
